Hi everybody
I always want to build a tube guitaramp (and a bassamp too if I could - I play both) for myself. I would like to build that amp using a preamp like JCM800 with an FX loop, but the poweramp not use tubes like EL34 or 6L6 or smth else because those are too popular => too expensive in my country. My idea is using those Russian military grade tubes like GU-50 or 6C33C (am I crazy 😀), because those tubes are still cheap, easy to find NOS ones in my country & of course, very durable. The preamp & FX loop would use 6N2P-EV & 6N1P-EB military tubes too.
The problem is that I only have enough knowledge to read schematic, work with tube, soldering... BUT not to design something new , so I don't know how to use those GU-50s & 6C33Cs for a guitaramp. Do a search with Mr.Google & I find some schematics using GU-50 PP, 6C33C PP OTL ( I think the poweramp stage should be PP or PPP class AB, and OTL for 6C33C) ; but all of them are for Hi-fi/Hi-end uses, I don't know if I can use them for my poweramp. Can you guys help me solve this problem? Any advise would be great 🙂
Thanks
P.S: - my English sucks, i'm sorry

Thanks alot, Miles 🙂Miles Prower said:
Looks like it would take me months or more for a noob like me to understand all those knowledge, but I'll try, I promise 😀
But actually the main thing I want to ask how to use tubes like GU-50 or 6C33C (I prefer GU-50) in a poweramp stage of an guitaramp, instead of those popular ones like EL34, 6L6GC, 6550... Any change/mod should I do with the original schematics (JCM800...) or must I use completely new schematic to use the GU-50 etc... these kind of advise would be more helpful, not that i'm too lazy (actually i am 😉 ) to read Miles' tutorial but it would cost a lot of time for me to read, learn and design a new whole amp 🙄
